Hello every1.
Have the problem with low FPS (~8-12 FPS instead old amount of 35-45) after reinstalling windows.
What i've done:
Just reinstalled my OS on the same one - Windows 7 Prof x64 SP1.
My specs are:
i5-3470 3.2 GHz
8 Gb RAM
NVidia GeForce GTX 660 2Gb
All OS updates are installed already. Also i tried the last NVidia driver version and the version of January 2017 - no beans.
Help me to find the source of problem please.

Will be great if next patch will provide:
- free look
- auto-confirmation of chosen respawn point when the timer ticks out
- removing false reloading of weapon even if no shots was fired from current clip (i'm often press R while in game to keep my weapon ready)
- some response from US side to russian BTR (the same class of APC that could support/transport infantry). AFM the BTR is more powerful than HMMV
- at least one type of heli (even if it would be a recon chopper without any weaponry) just to add some action in such a beautiful sky
- frag grenades for grenadier kit
- deployment ability for MG and marksman weapon
- collimator optic
- silenced weapons (at least pistols for sniper kit and rifle for marksman as in PR)
- SNIPER kit
- KNIFES!
